John Diomede has practiced pharmacy since 1981, working in retail, corporate, and hospital settings. He holds a Ph.D. in Health Administration and is an ordained minister with decades of independent biblical study and pastoral experience. A successful entrepreneur, he owned and operated his own retail pharmacy and has spent more than forty years helping people navigate health, risk, and real-world consequences.

Through his writing, he brings the same diagnostic clarity to spiritual questions—examining illusion, identity, and the voice of the Holy Spirit. John is married, the father of five married sons, and the grandfather of eight.
